A redated post.
My first published paper, "Miracles and the Case for Theism" replied to Mackie's treatment of miracles in The Miracle of Theism. I discovered a formal error in Mackie's analysis, which violates the Mackie Revelance Principle. The paper came out in February 1989 International Journal for Philosophy of Religion. And, of course, a follow-up treatment of miracles is on Internet Infidels. Someone who wants to defend Mackie's or Hume's position might want to start by rebutting me in those papers.
